To all *whom t may concern.'

Be it known that l, Groen J osnr'iiC/on'r 'ing the properties of rubbing plates anda liquid for absorbing shocks.

Another object ofthe invention is to provide a shock absorber of this type provided with means for adjusting the rubbing action of the plates so that the plates will bear with more or less friction against adjacent. plates. I

Aanother object of the invention is to lfur-` nish a rubbing plate shock absorber in which the plates are provided with grooves which permit the passage of the shock absorbing fluid between the plates.

Vith theforegoing objects outlined`r and with other objects in view which will appear as the description proceeds the invention consists in the novel features hereinafter described in detail, illustrated in the accom- )an 'inv' drawinU and more aarticularlf #D C .d

pointed out in the appended claims,

Referring to the drawing: Figure 1 is a longitudinal sectional view of the improved shock absorber.

2 is a transverse sectional view of the same taken on line 2--2l of Fig. 1.

Fig. 3 is aperspective view of one of the plates employed in the absorber.

ln the drawing, 1 designates a casing or receptacle having a cover 2 provided with iilling aperture 3- closed by a cap a. The casing is provided on one side with a half collar 5 designed to cooperate with a second half collar 6 and fastening means 7 for securing the casing to the axle 8 of a vehicle. A bolt. 9 connects opposite walls of the casing and extends through the lowerportion of the interior of the casing, andis provided at one end with a nut 10 to permit its attachment and detachment from the casing. Mounted on the bolt 9 is a series of platesA relatively to each other.

11 each having an" apertured ear 12 at its lower end through which the bolt passes.- Spacing collars 13' aremounted on the ibolt to'space theplates apart. The casing is "preferably provided with a vertical post 14 having a bifurcated upper end 15 which carriesa' pivotally mounted lever 16. One end of the lever is provided with a plurality 'of aperture 17 to permit the lever to be adjustably connected to a vehicle spring (not shown). The other end of the lever is connectedby a pin 18 to the bifurcated upper end of a reciprocating rod 19. This rod passes through a packing gland 2O and its lower endlis connected to a `bolt. 21 having a .nut v22'at one of its ends.r

This bolt passes through ears 23 in the upper ends of sliding plates 24 which operate in the spaces between `the platesy 11. The bolt 21 is providedwith vspacing collars 25 to space the vplates 241 apart.

. @ne of the rubbing plates'v is illustrated vin Fig. 3 and it consistsof'asubstantially rectangular ilat member provided on its oppoe site sides with'oil channels 27. Leaf springs 2S bear against the outer sides of the outer plates 11 and extension screws 29 are provided for the purpose of adjusting these springs. In operation the casing 1 is substantially filled with oil or a similarliquid and when a shoclr occurs the plates 2a and 11 move This causes oil to pass through the channels 27, and the oil passing through these restricted passageways functions to absorb the shock.

It is not desired to limit the invention to this specilic purpose or specilic form, buty the detail description of this special ap-v paratus is for the purpose of presenting a repaired 1100 be readily understood by those skilled in 1o5 the art and I am aware that various changes be made in the construction shown without departing from the spirit of the 1nventionas expressed .o in the following claimsd l v What I claim and desire to lsecure by Letters-Patent is `l. A shock absorber comprising a casing adapted to contain a liquid, aseries of relatively stationary spaced plates mounted in said casing, a series oi' reciprocating plates arranged between the other plates and adapted to displace liquid between said stationary plates, an actuating;v memberr engaging the movable plates, and means for constantly forcing` said plates toward one another. -v

2. A shock absorber comprising` a casing adapted to contain a liquid, a series of relaby claim'2 in which they irst mentioned plates are provided with channels to permit thepassage of the'liquid within thecasing. 4L. A shock absorber of the kind defined b v claim 2 in which' the second mentioned plates are providedwith channels to permit the passage of the liquid. l

-5. A shock` absorber of the kind defined by claim 2in which the plates are provided with channelsto permit thepassage of liquid betweenk the plates. f Y

6. A. shock absorber of the-kind defined bv claim'2 in which the means Jfor forcing the plates together includes leai springs and adjusting screws. n

7. A shock absorber of the kind defined by claim 2 in which the casing is provided with a bracket for securing the same to an axle, a post `connected to the casing, and a lever pivotally mounted on the post and connected to the operating member of the movable plates.

8. ifi shock absorber comprising` a casinghaving` a removable cap and adapted to contain a liquid, a bolt extending through said casing `from one side wail to an opposite side wall, a series of fixed plates connected to rsaid bolt a rod slidably mounted in thc cover of said casing, a series of spaced movable plates carried b v said rod and arranged between the fixed plates, and acljnstableri silient means for forcing`- said plates to- 4Qether.

A shock absorber of the kind delined bv claim 8 in which the plates are provid-cd with channels to permit the passage of liquid between the same.'

i0. A, shock absorber of the kind defined bv claim S in which the means for 'forcing' the plates together includes lent' springs and adj usting screws.
